Welcome to the forum Ben.
With the length and quality of the clip it is not possible to discern what is you talking and what is a response.
If you can post a clip of 60 seconds it may make more sense.
We also have to take noise contamination into consideration, so would help to know the location, time of day and anyone else present or around the area.
At the moment from one small clip I can't determine if it is something or not.
Have you kept a diary or log of this location, and if so is there anything else happening? Paranormal events are rare in isolation, and usually other things are happening as well.
